M51, the Whirlpool Galaxy (aka Galaxy 9), has been giving me grief this year. I’ve tried to image it a few times but something happened each time. Finally, Thursday night I was able to get a decent image. This is made from 44 two minute images with my C11 at f/6.3 with an Antlia Quadband light pollution filter and my ZWO ASI294MC Pro. I started with 51 images but seven of them had satellite trails in them.
